To get an idea of exactly how small the worldâs smallest insect is, take out a ruler and look at those tiny lines that appear in between centimeters (make sure youâre not on the side that measures in inches). If in doubt, ask a grown-up to help you find the millimeters.
Diarrhea can also cause weight loss. Abdominal pain is another symptom of colon cancer that may prevent you from eating normally. If you have lost a significant amount of weight accompanied with these symptoms, you need to talk to your doctor immediately to determine the cause.
Vomiting (throwing up) and diarrhea (frequent, watery bowel movements) can be harmful because they can cause dehydration. Dehydration occurs when you lose too much fluid. Vomiting and diarrhea can be caused by a number of things, including viruses, bacteria, parasites, certain medicines, or certain medical conditions. Foods that are hard to digest (such as too many sweets) and undercooked (raw or partially raw) meat or fish can also cause vomiting and diarrhea.
